HEATING Dn'vrcn. I

To all whom it may concern:

Be it known that we, CARROLL M'. TAYLOR and WALTER R. SHEARER, citizens of the United States, residing at Coatesville, county of Chester, and State of Pennsylvania, and Hanover, county of York, and State of Pennsylvania, have invented certain new `and useful Improvements in Heating Devices, of which the following is a specication.

Our invention consists of an improved form of heating device, and is particularly serviceable for use on automobiles or other vehicles employing internal combustion en` gines, and which derive their power vfrom 'the explosion of gases within piston cylin- One of the objects of our invention is to .utilize the hot' exhaust gases as they are expelled from the engine and pass these gases through a radiator within the automobile.

` Another object is to control the passage of the exhaust gas so that it will efficiently heat theA radiator withoutl producing noise. -A still further object is to so control the heatedv exhaust gas for heating purposes so that no back pressure-will. result in the engine, .thus preventing the choking of the engine which would otherwisev occur if the exhaust was not permitted to freely vpass to the atmosphere. A

A furtherobject is to so construct our `invention that it may be quickly and cheaply installed in automobiles, or power driven vehicles of any description.

A further object is to provide'the device with p means for operating valves therein, so that the exhaust may be cut off from the radiator or that a part ofthe exhaust`l may rbe caused to circulatethrough the radiator.

A further Objectis to so construct thedevice thata free circulation will be set up within the radiator without the inclusion of expensive or complicated mechanisms.

These objects, and other advantageous ends which will be described hereinafter, we attain in the following manner, reference be- -ing had to the accompanying drawings in which- Figure 1 is a sectional elevation of a porv tion of an .automobile showing our invention thereon( e Fig. 2 is Aan 'enlarged sectional view through the principal elements of our invention. f i

Specification of Letters Patent.

Fig. 3ds a fragmentary section showing a modified form of the elements showny in Fig. 2. y

Referring to the drawings, 1 represents the body of an automobile having an engine 2, and 3 is the exhaust pipe through which the hot exhaust gas passes outwardly from the engine.

Considering Figs. 1 and 2 of the drawings, an inclosed tank isinterposed between the sections 5 and 6 of the exhaust pipe 3, andy this tank 11 is of greater cross section than the exhaust pipe 3, so as to provide an enlarged chamber 7 into which the gas after passing through the section 5 of which is connected with the upper end of a' pipe 12. t

The portion 13 ofthis pipe 12 is inclined and enters the section 6 of the exhaust pipe.

a slant, said slant being in the generaldlrectlonA of the lpassage of gases through the section 6 as `indicated by theV arrow in Fig, 1, so that any gas passing downwardly through the pipe 12 will enter the section 6 of the vexhaust pi )e 3 and Continue in the direction of they exliaust as indicated by said arrow. f

A valve 14 is' pivotally connected between the opening in the upper portion of the tank 4 and theadjacent end of the pipe'S, and this valve is operated, through the medium of a crank arm 15, link 16, lever 17, and intermeshing worm wheel and Worm 18 and 19 respectively, by a hand wheel 2O conveniently located within the body of the automobile, softhat a rotation lof said hand ywheel will cause the valve 14 to move into an open or closed position to permit or cut olf communication between the radiator 10 and the chamber 7 Another valve 21 is pivotally mounted 105 within the sect-ion 6 of the exhaust pipe 3 at a point intermediate of the tank 4 and the entrance of the pipe 12 with the section 6. This valve 21 is moved by elements similar to those described in connection with thejvalve 14, so that it may be moved at right angles to the pipe section 6, or at any other angledesired.

, it, and the remainder of the gas Will pass through the section 6 to the atmosphere.V At times when it is desired to secure a rapid initial heating of the radiator, the valve 2l may be closed or partially closed, thereby compelling a greater amount of the exhaust gas to pass through the pipe 8 and radiator 10. However, after the radiator has been heated to a desired degree, the valve 21 should be moved to its full open position,

' since it will be notedthat the ordinary operating condition of our invention, for example as illustrated in F ig. 3 of the drawing, is witlrthe valves 14 and 21 fully open and under such condition there is afree circulation of the heated gas through the radiator.

By providing the large chamber 7 and having the portion 13 ofthe pipe 12 extending at an angle as above described, a free circulation of the heated gas is secured through the radiator, and the chamber 7 within the 'tank 4 acts as a calming chainbern which permits the intermittent discharges ofthe gas from the engine to spread out and combinel due to their expansive force, and as the pipe 8 communicates with the upper portion of the -chamber 7, the heated gas rises to the top of said chamber and passes upwardly into the radiator.

The entrance oi the sections 5 and 6 of the exhaust pipe 3 is preferably made adjacent thc bottom of the chamber 7, so that there is a. space 22 which acts as a reservoir for a certain amount of the heated gas, thus permitting the-latter-mentioned portion of the gas to freely pass upwardly through the pipe 8. The other portion of the gasl within the chai'noer 7 will pass outwardly through the section 6, and in doing so will tend to suck the gas downwardly through the portion 13 of the pipe 12, thereby accelerating the circulation within the radiator, and insure an efficient heating of the radiator without choking the exhaust pipe.

It will be noted that thev tank 4 will also act in the capacity of a muiiler to deaden the noise which would otherwise occur from the direct discharges of the gas from the engine. Therefore the tank 4 acts in two capacities as-a' calming chamber of which the upper portion provides a reservoir. -for a certain amount of the heated gas to pass through to the diameter of the section (i of the exhaust pipe.

The inlet section 5 of the exhaust pipe is in communication with the opening 36 in the casing 33 at the large end thereof. The pipe 8 is in communication with an opening 37 in the extreme uppermost portion Aof the tank 33, and extends to the radiator, the latter also having the pipe portion 13 leading at an angle to the section 6 in the same manner as shown in -connection with Figs. 1 and 2 of the drawing.

In some instances, the construction shown in Fig. 3 may be preferred to the construction shown in Fig. 2, since the tapered upper Wall of the tank 33 causes a certain amount of the heated gas to pocket adjacent the opening 37 and readily pass upwardly through the pipe 8 when its valve is open.

If it is desired to cut off the heat to the radiator 10, the wheel 20 may be turned which causes a movement of the lever 17, link 16, and .crank arm 15 to move the valve 14 into its closed position.

By having the worm and worm wheel connection for operating the valves, there is 'practically no possibility of these valves being opened or closed by the vibration of the car or engine, since it would be necessary for the worm to rotate before the worm wheel could move even to the extent of one tooth.

1n certain of the claims we have used the term outlet section of the exhaust pipe proper by which is meant the outlet section of the exhaust pipe independent of any muiiler or other device. However, it will be understood that a mufiier of anytype may be added to the exhaust pipe if desired.

While we have described our invention as taking a particular form, it will be understood that the various parts of our invention may be changed without departing trom the spirit thereof, and hence we do not limit ourselves to the precise construction setforth, but consider that we are at liberty to make such changes and alterations as fairly come within the scope of the appended claims. f

Having thus described our invention what we claim as new and desire to secure by' munication with two sections of the exhaust l pipe, a closed radiator having an inlet and an outlet passage, a pipe communicating with the inletl passage of the radiator and with the chamber, a second pipe of smaller cross section than the outlet section of .the exhaust pipe and communicating with the .outlet passage of the radiator and with the outlet section of the exhaust pipe proper Within its length, and a valvefor regulating the passage of gas through the radiator and being operative independently of the exhaust pipe so asnot to prevent passage of the gas therethrough, substantially as de-` scribed.
